The use of extendible distal femoral replacements is a relatively new treatment alternative for malignant bone tumours in growing individuals. Although their appearance was widely appreciated, questions about functional practicality and longevity remain unclear. With longer follow-up, advantages of immediate functional restoration and beneficial psychological aspects seem to be overshadowed by an increase in complications such as aseptic loosening, infection or prosthetic failure.

Figures and Tables from this paper

Extendible replacements of the proximal tibia for bone tumours.
TLDR
The use of extendible prostheses of the proximal tibia remains an experimental procedure and the technique is now using a simpler, minimally invasive, technique which the authors hope will decrease the incidence of complications.
Extensible Endoprostheses for Bone Tumors of the Proximal Femur in Children
TLDR
Extensible endoprosthesis of the proximal femur is a viable alternative to hip disarticulation and in selected children offers an opportunity for near-normal development of the lower limb by allowing equalization of limb length and the ability to walk without the use of mobility aids.
Non-invasive distal femoral expandable endoprosthesis for limb-salvage surgery in paediatric tumours.
TLDR
The implant avoids multiple surgical procedures, general anaesthesia and assists in maintaining leg-length equality and complications developed in two patients; one developed a flexion deformity at the knee joint, which was subsequently overcome and one died of disseminated disease.
Use of irradiated autologous bone in joint sparing endoprosthetic femoral replacement tumor surgery
TLDR
Encouraging results are reported utilizing irradiated autologous proximal femoral bone combined with distal femoral replacement in skeletally immature patients.
Endoprosthetic reconstruction of the distal tibia and ankle joint after resection of primary bone tumours.
TLDR
A custom-made endoprosthetic replacement of the distal tibia and ankle joint is a viable treatment option for carefully selected patients with a primary bone tumour and patients should be informed of the risk of infection and the potential need for amputation if this cannot be controlled.
Endoprosthetic replacement of the distal femur for bone tumours: long-term results.
TLDR
It is believed that a cemented, rotating-hinge prosthesis with a hydroxyapatite collar offers the best chance of long-term survival of the prosthesis.
Outcomes of Fixed-Hinged Knee Prosthesis for Distal Femoral Osteosarcoma in Skeletally Immature Patients: First Results.
TLDR
This hinged knee prosthesis can keep the growth potential in the adjacent tibia, provides satisfying functional outcomes, and has a lower postoperative complication rate, and could serve as an alternative intervention for distal femoral osteosarcoma in skeletally immature patients.
Functional outcome study of mega-endoprosthetic reconstruction in limbs with bone tumour surgery.
TLDR
Mega-endoprosthetic reconstruction in limb salvage provides good functional outcome in patients with bone tumours and there is no statistical difference in the functional outcome between upper limb and lower limb procedures, and between hip and knee procedures.
Expandable distal femur megaprosthesis: A European Musculoskeletal Oncology Society study on 299 cases.
TLDR
This study shows the increasing popularity of expandable distal femur prostheses, with overall good results for function and implant survival, however, repeat surgery is frequently required, especially in patients under the age of 10 years old.
Expandable endoprosthesis for limb-sparing surgery in children: long-term results
TLDR
A significant correlation was found between function and final LLD, the number of complications, and thenumber of surgical procedures performed other than prosthesis elongation, the younger the patient was at definitive surgery, the shorter the time it took for the prosthesis to fail.

STANMORE CUSTOM-MADE EXTENDIBLE DISTAL FEMORAL REPLACEMENTS: CLINICAL EXPERIENCE IN CHILDREN WITH PRIMARY MALIGNANT BONE TUMOURS
TLDR
18 children with malignant bone tumours who were treated between 1983 and 1990 by custom-made Stanmore extendible distal femoral replacements are reviewed, finding that advantages of immediate functional restoration and beneficial psychological aspects seem to be overshadowed by an increase in complications.
Prosthetic replacement of the distal femur for primary bone tumours.
TLDR
It is concluded that prosthetic replacement of the distal femur can meet the objectives of limb salvage surgery.
Expandable endoprosthetic reconstruction of the skeletally immature after malignant bone tumor resection.
TLDR
Preliminary results suggest that expandable endoprostheses do offer an alternative to amputation and rotationplasty as a means of local control and extremity reconstruction in children with primary malignant bone tumors.
Extendable tumour endoprostheses for the leg in children.
TLDR
Implantation of extendable endoprostheses in children provides a reasonable alternative to rotationplasty, but limb salvage requires more operations.
Distal femoral replacement by custom-made prostheses. Clinical follow-up and survivorship analysis.
TLDR
Long-term clinical follow-up and survivorship analysis of 40 distal femoral replacements performed between 1964 and 1980 for traumatic, locally aggressive and malignant conditions showed a cumulative success rate of 80% at eight years, with no subsequent deterioration at 18 years.
Aseptic loosening in cemented custom-made prosthetic replacements for bone tumours of the lower limb.
TLDR
Young patients with distal femoral prostheses in whom a high percentage of the femur had been replaced had the poorest prognosis for survival without aseptic loosening, and neither the age nor the percentage of bone removed was a factor after proximal femoral replacement.
Endoprosthetic replacement for stage IIB osteosarcoma.
TLDR
The functional results were good overall, with excellent results seen in distal femoral reconstruction, and the intermediate-term results, with a median follow-up period of 43 months, remains encouraging.
Uncemented intramedullary fixation of implants using polyethylene sleeves. A roentgenographic study.
TLDR
A sclerotic interface around the polyethylene sleeves invariably developed and progressed in density up to 28 months postoperatively, and there were significant zonal differences in sclerosis, particularly between the plateau and the mid-sleeve zone.
